Abstract
A multiple position adjustable exercise device includes a first plate, a second plate and an elastic member. The second plate is pivotally connected with the first plate. The elastic member is disposed between the first plate and the second plate, and when the second plate rotates relative to the first plate, the elastic member is twisted for providing an elastic recovering force. An initial position of the second plate relative to the first plate is adjustable for adjusting the elastic recovering force.
Claims2
A multiple position adjustable exercise device, comprising:
- a lever;
- a base, wherein the lever is pivotally connected with the base;
- an accommodating device disposed on the base;
- an elastic member disposed in the accommodating device, wherein when the lever rotates relative to the base, the elastic member is stretched or compressed for providing an elastic recovering force;
- a pivoting axis, wherein one end of the pivoting axis is pivotally connected with one end of the lever;
- a belt, wherein the other end of the pivoting axis is connected with one end of the belt, and the other end of the belt is connected with the elastic member;
- and
- at least one guiding wheel, wherein the belt is linked with the pivoting axis through the guiding wheel;
- wherein an initial position of the lever relative to the base is adjustable for adjusting the elastic recovering force;
- wherein when the lever rotates relative to the base, the pivoting axis is linked by the lever, and the belt is moved by the guiding wheel for stretching or compressing the elastic member.
